2 - SAFETY PRECAUTIONS

2-1. KICKBACK SAFETY PRECAUTIONS

WARNING

Kickback may occur when the nose or tip of the guide bar

touches an object, or when the wood closes in and pinch-

es the saw chain in the cut. If bar tip makes contact with

something it may cause a lightning-fast reverse reaction,

kicking the guide bar up and back towards the operator.

Pinching the saw chain along the top of the guide bar may

push the guide bar rapidly back towards the operator. Either

of these reactions may cause you to lose control of the saw,

which could result in serious personal injury. Do not rely

exclusively upon the safety devices built into your saw. As

a chain saw user, you should take several steps to keep

your cutting jobs free from accident or injury.

1. With a basic understanding of kickback, you can

reduce or eliminate the element of surprise. Sudden

surprise contributes to accidents.

2. Keep a good firm grip on the saw with both hands, the

right hand on the rear handle, and the left hand on the

front handle, when the engine is running. Use a firm

grip with thumbs and fingers encircling the chain saw

handles. A firm grip will help you reduce kickback and

maintain control of the saw. Don’t let go.

3. Make sure that the area in which you are cutting is

free from obstructions. Do not let the nose of the guide

bar contact a log, branch, or any other obstruction

which could be hit while you are operating the saw.

4. Cut at high engine speeds.

5. Do not overreach or cut above shoulder height.

6. Follow manufacturer’s sharpening and maintenance

instructions for the saw chain.

7. Only use replacement bars and chains specified by

the manufacturer or the equivalent.

specified in ANSI B175.1-2000.

2-2. OTHER SAFETY PRECAUTIONS

1. DO NOT operate a chain saw with one hand! Serious

injury to the operator, helpers, bystanders, or any

combination of these persons may result from one-

handed operation. A chain saw is intended for two-

handed use.

DO NO

T oper

ate a chain sa

3. Use safety footwear, snug-fitting clothing, protective

gloves, and eye, hearing and head protection devices.

4. Use caution when handling fuel. Move the chain saw

at least 9.1m (30 feet) from the fueling point before

starting the engine.

5. DO NOT allow other persons to be near when starting

or cutting with the chain saw. Keep bystanders and

animals out of the work area.

6. DO NOT start cutting until you have a clear work area,

secure footing, and a planned retreat path from the

falling tree.

7. Keep all parts of your body away from the saw chain

when the engine is running.

8. Before you start the engine, make sure that the saw

chain is not contacting anything.

9. Carry the chain saw with the engine stopped, the

guide bar and saw chain to the rear, and the muffler

away from your body.

10. DO NOT operate a chain saw that is damaged,

improperly adjusted, or not completely and securely

assembled. Be sure that the saw chain stops moving

when the throttle control trigger is released.

11. Shut off the engine before setting the chain saw down.

12. Use extreme caution when cutting small size brush

and saplings because slender material may catch the

saw chain and be whipped toward you or pull you off

balance.

13. When cutting a limb that is under tension, be alert for

springback so that you will not be struck when the ten-

sion in the wood fibers is released.

14. Keep the handles dry, clean, and free of oil or fuel mix-

ture

15. Operate the chain saw only in well-ventilated areas.

16. DO NOT operate a chain saw in a tree unless you

ve been specifically trained to do so.

17. All chain saw service, other than the items listed in the

user manual safety and maintenance instructions,

should be performed by competent chain saw service

personnel.

18. When transporting your chain saw, use the appropri-

ate guide bar scabbard.

19. DO NOT operate your chain saw near or around flam-

mab

le liquids or gases whether in or out of doors. An

explosion and/or fire may result.

20.

USE THE RIGHT TOOL: Cut wood only. Do not use

SAFETY PRECAUTIONS FOR CHAIN SAW USERS

(ANSI B175.1-2000, Annex C. CAN/CSA-Z62.1-03)

NOTE: These safety precautions are intended primarily for

the consumer or occasional user. When using a chain saw

for logging purposes, refer to the Code of Federal

Regulations, Section 1910.226(5); 2.5.1., of American

National Standard Safety Requirements for Pulpwood

Logging, ANSI 03.1-1978; and relevant state safety codes.

These models are classified according to CAN/ CSA-

Z62.1-03 as a Class 1C saw. They are intended for infre-

quent use by homeowners, cottagers, and campers, and for

such general applications as clearing, pruning, cutting fire-

wood, etc. They are not intended for prolonged use. If the

intended use involves prolonged periods of operation, this

may cause circulatory problems in the user’s hands due to

vibration. All models covered in this manual employ an anti-

vibration feature for increased comfort and safety.

2-3. GENERAL SAFETY PRECAUTIONS

FOR CHAIN SAW USERS

1. Fatigue causes carelessness. Be more cautious

before rest periods and towards the end of your shift.

2. Personal protective clothing required by your safety

organizations, government regulations, or your

employer should be used. At all times when using a

chain saw, snug-fitting clothing, protective eye wear,

safety footwear, and hand, leg, and hearing protection

should be worn.

3. Before refueling, servicing, or transporting your chain

saw, switch off the engine. To help prevent fire, restart

your chain saw at least 9.1m (30ft) from the fuelling

area.

4. When a chain saw is being used, a fire extinguisher

should be available.

5. When felling, keep at least 2 tree lengths away from

your fellow workers.

6. Plan your work, ensuring an obstacle-free work area

and, in the case of felling, at least one escape path

from the falling tree.

ollo

w the instructions in your operator’s manual for

starting the chain saw and control the chain saw with

a fir

m g

rip on both handles when it is in operation.

Keep handles dry, clean, and free of oil.

8. When transporting your chain saw, use the appropri-

ate tr

anspor

tation co

ers

, which should be available

for the guide bar and saw chain.

9. Never operate a chain saw that is damaged or improp-

erly adjusted or that is not completely and securely

assemb

led.

Be sure that the saw chain stops moving

when the power control system trigger is released.

ver adjust the guide bar or saw chain when the

engine is operating.

10.

Beware of carbon monoxide poisoning. Operate the

chain sa

w in w

ell-v

entilated areas only

11. Do not attempt a pruning or limbing operation in a

standing tree unless specifically trained to do so.

12. Guard against kickback. Kickback is the upward

motion of the guide bar that occurs when the sa

chain, at the nose of the guide bar, contacts an object.

Kickback can lead to dangerous loss of control of the

chain saw.

13. A chain saw is intended for two-handed use. Serious

injury to the operator, helpers, and/or bystanders can

result from one-handed oper

ation.

14. See section 2-5, 2-6 for symbol definitions, page 5.

15. When carrying a chain saw with the engine running,

engage the chain brake.

16. Allow your chain saw to cool before refueling, and do

not smoke.

17. Keep other persons or animals a safe distance away

from a running chain saw or the area where a tree is

being felled.

18. Use extreme caution when cutting small brush and

saplings because slender material can catch the saw

chain and be whipped toward you.

19. When cutting a limb that is under tension or compres-

sion, be alert for springback.

20. This gas-powered saw is classified according to CAN/

CSA-Z62.1-03 as a Class 1C saw. It is intended for

infrequent use by homeowners, cottagers, and

campers, and for such general applications as clear-

ing, pruning, cutting firewood, etc. It is not intended for

prolonged use.

Prolonged periods of operation can cause circulatory

problems in the user’s hands due to vibration. For

such use, it may be appropriate to use a saw having

an anti-vibration feature.

2-4. MORE ABOUT KICKBACK

WARNING

DANGER! BEWARE OF KICKBACK!

Kickback can lead to dangerous loss of control of the chain

saw and result in serious or fatal injury to the saw operator

or to anyone standing close by. Always be alert. Rotational

kickback and pinch-kickback are major chain saw opera-

tional dangers and the leading cause of most accidents.

NOTE: These safety precautions are intended primarily for

the consumer or occasional user. When using a chain saw

for logging purposes, refer to the Code of Federal

Regulations, Section 1910.226(5); 2.5.1., of American

National Standard Safety Requirements for Pulpwood

Logging, ANSI 03.1-1978; and relevant state safety codes.

These models are classified according to CAN/ CSA-

Z62.1-03 as a Class 1C saw. They are intended for infre-

quent use by homeowners, cottagers, and campers, and for

such general applications as clearing, pruning, cutting fire-

wood, etc. They are not intended for prolonged use. If the

intended use involves prolonged periods of operation, this

may cause circulatory problems in the user’s hands due to

vibration. All models covered in this manual employ an anti-

vibration feature for increased comfort and safety.

2-3. GENERAL SAFETY PRECAUTIONS

FOR CHAIN SAW USERS

1. Fatigue causes carelessness. Be more cautious

before rest periods and towards the end of your shift.

2. Personal protective clothing required by your safety

organizations, government regulations, or your

employer should be used. At all times when using a

chain saw, snug-fitting clothing, protective eye wear,

safety footwear, and hand, leg, and hearing protection

should be worn.

3. Before refueling, servicing, or transporting your chain

saw, switch off the engine. To help prevent fire, restart

your chain saw at least 9.1m (30ft) from the fuelling

area.

4. When a chain saw is being used, a fire extinguisher

should be available.

5. When felling, keep at least 2 tree lengths away from

your fellow workers.

6. Plan your work, ensuring an obstacle-free work area

and, in the case of felling, at least one escape path

from the falling tree.

ollo

w the instructions in your operator’s manual for

starting the chain saw and control the chain saw with

a fir

m g

rip on both handles when it is in operation.

Keep handles dry, clean, and free of oil.

8. When transporting your chain saw, use the appropri-

ate tr

anspor

tation co

ers

, which should be available

for the guide bar and saw chain.

9. Never operate a chain saw that is damaged or improp-

erly adjusted or that is not completely and securely

assemb

led.

Be sure that the saw chain stops moving

when the power control system trigger is released.

ver adjust the guide bar or saw chain when the

engine is operating.

10.

Beware of carbon monoxide poisoning. Operate the

chain sa

w in w

ell-v

entilated areas only

11. Do not attempt a pruning or limbing operation in a

standing tree unless specifically trained to do so.

12. Guard against kickback. Kickback is the upward

motion of the guide bar that occurs when the sa

chain, at the nose of the guide bar, contacts an object.

Kickback can lead to dangerous loss of control of the

chain saw.

13. A chain saw is intended for two-handed use. Serious

injury to the operator, helpers, and/or bystanders can

result from one-handed oper

ation.

14. See section 2-5, 2-6 for symbol definitions, page 5.

15. When carrying a chain saw with the engine running,

engage the chain brake.

16. Allow your chain saw to cool before refueling, and do

not smoke.

17. Keep other persons or animals a safe distance away

from a running chain saw or the area where a tree is

being felled.

18. Use extreme caution when cutting small brush and

saplings because slender material can catch the saw

chain and be whipped toward you.

19. When cutting a limb that is under tension or compres-

sion, be alert for springback.

20. This gas-powered saw is classified according to CAN/

CSA-Z62.1-03 as a Class 1C saw. It is intended for

infrequent use by homeowners, cottagers, and

campers, and for such general applications as clear-

ing, pruning, cutting firewood, etc. It is not intended for

prolonged use.

Prolonged periods of operation can cause circulatory

problems in the user’s hands due to vibration. For

such use, it may be appropriate to use a saw having

an anti-vibration feature.

2-4. MORE ABOUT KICKBACK

WARNING

DANGER! BEWARE OF KICKBACK!

Kickback can lead to dangerous loss of control of the chain

saw and result in serious or fatal injury to the saw operator

or to anyone standing close by. Always be alert. Rotational

kickback and pinch-kickback are major chain saw opera-

tional dangers and the leading cause of most accidents.

TO INSTALL SAW CHAIN:

WARNING

Always wear heavy duty gloves when handling saw chain

or making sa

w chain adjustments.

1. Spread chain out in a loop with cutting edges (A)

pointing CLOCKWISE around loop (Figure 3-3F).

2. Slip the chain around the sprocket (B) behind the

clutch (C). Make sure the links fit between the sprock-

et teeth (Figure 3-3G).

3. Guide the drive links into the groove (D) and around

the end of the bar (Figure 3-3G).

NOTE: The saw chain may droop slightly on the lower part

of bar. This is normal.

4. Pull guide bar forward until chain is snug. Ensure all

drive links are in the bar groove.

5. Install the clutch cover making sure the tang is posi-

tioned in the lower hole in the guide bar. Make sure

the chain does not slip off of the bar. Install the bar

retaining nuts hand tight and follow tension adjust-

ment instructions in Section 3-4.

NOTE: The guide bar retaining nuts are installed only hand

tight at this point because saw chain adjustment is

required. Follow instructions in Section 3-4, Saw Chain

Tension Adjustment.

3-4. SAW CHAIN TENSION ADJUSTMENT

Proper tension of saw chain is extremely important and

must be checked before starting, as well as during any cut-

ting operation.

Taking the time to make needed adjustments to the saw

chain will result in improved cutting performance and pro-

longed chain life.

WARNING

Always wear heavy duty gloves when handling saw chain

or making saw chain adjustments.

TO ADJUST SAW CHAIN:

1. Hold nose of guide bar up and turn adjustment screw

(D) CLOCKWISE to increase chain tension. Turning

screw COUNTERCLOCKWISE will decrease amount

of tension on chain. Ensure the chain fits snugly all the

way around the guide bar (Figure 3-4A).

2. After making adjustment, and while still holding nose

of bar in the uppermost position, tighten the bar

retaining nuts securely. Chain has proper tension

when it has a snug fit all around and can be pulled

around by gloved hand.

NOTE: If chain is difficult to rotate on guide bar or if it binds,

too much tension has been applied. This requires minor

adjustment as follows:

A. Loosen the bar retaining nuts so it is finger tight.

Decrease tension by turning the bar adjustment screw

COUNTERCLOCKWISE slowly. Move chain back and

forth on bar. Continue to adjust until chain rotates

freely, but fits snugly. Increase tension by turning bar

adjustment screw CLOCKWISE.

B. When saw chain has proper tension, hold nose of bar

in uppermost position and tighten the bar retaining nut

securely.

3 - ASSEMBLY INSTRUCTIONS

CAUTION

A ne

w saw chain stretches, requiring adjustment after as

few as 5 cuts. This is normal with a new chain, and the

interval between future adjustments will lengthen quickly.

CAUTION

If saw chain is TOO LOOSE or TOO TIGHT, the sprocket,

bar, chain, and crankshaft bearings will wear more rapidly.

Study Figure 3-4B for information concerning correct cold

tension (A), correct warm tension (B), and as a guide for

when saw chain needs adjustment (C).

3-5. CHAIN BRAKE

MECHANICAL TEST

Your chain saw is equipped with a CHAIN BRAKE

that

reduces possibility of injury due to kickback. The brake is

activated if pressure is applied against brake lever when,

as in the event of kickback, operator’s hand strikes the

lever. When the brake is actuated, chain movement stops

abruptly.

WARNING

The purpose of the CHAIN BRAKE

is to reduce the possi-

bility of injury due to kickback; however, it cannot provide

the intended measure of protection if the sa

w is oper

ated

carelessly.

5-6.SAW CHAIN / BAR LUBRICATION

Adequate lubrication of the saw chain is essential at all

times to minimize friction with the guide bar.

Never starve the bar and chain of oil. Running the saw with

too little oil will decrease cutting efficiency, shorten saw

chain life, cause rapid dulling of chain, and cause exces-

sive wear of bar from overheating. Too little oil is evidenced

by smoke, bar discoloration or pitch build-up.

NOTE: Saw chain stretches during use, particularly when it

is new, and it will occasionally be necessary to adjust and

tighten it. New chain will require adjustment after about 5

min

utes of operation.

6 - GENERAL CUTTING INSTRUCTIONS

6-1.FELLING

elling is the term for cutting down a tree. Small trees up to

6-7 inches (15-18cm) in diameter are usually cut in a single

cut. Larger trees require notch cuts. Notch cuts determine

the direction the tree will fall.

FELLING A TREE:

WARNING

A retreat path (A) should be planned and cleared as nec-

essary before cuts are started. The retreat path should

extend back and diagonally to the rear of the expected line

of fall, as illustrated in Figure 6-1A.

CAUTION

If felling a tree on sloping ground, the chain saw operator

should keep on the uphill side of the terrain, as the tree is

likely to roll or slide downhill after it is felled.

NOTE: Direction of fall (B) is controlled by the notching cut.

Before any cuts are made, consider the location of larger

branches and natural lean of the tree to determine the way

the tree will fall.

WARNING

Do not cut down a tree during high or changing winds or if

there is a danger to property. Consult a tree professional.

Do not cut down a tree if there is a danger of striking utility

wires; notify the utility company before making any cuts.

GENERAL GUIDELINES FOR FELLING

TREES:

Normally felling consists of 2 main cutting operations,

notching (C) and making the felling cut (D).

Start making the upper notch cut (C) on the side of the tree

facing the felling direction (E). Be sure you don t make the

lower cut too deep into the trunk.

The notch (C) should be deep enough to create a hinge (F)

of sufficient width and strength.

The notch should be wide

enough to direct the fall of the tree for as long as possible.

WARNING

Never walk in front of a tree that has been notched.

Make the felling cut (D) from the other side of the tree and

1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C)

(Figure 6-1B).

Never saw completely through the trunk. Always leave a

hinge

. The hinge guides the tree. If the trunk is completely

cut through, control over the felling direction is lost.

Insert a wedge or felling lever in the cut well before the tree

becomes unstable and starts to move. This will prevent the

guidebar from binding in the f

elling cut if y

ou ha

ve mis-

judged the f

alling direction.

Mak

e sure no b

ystanders ha

entered the range of the falling tree before you push it over.

WARNING

Before making the final cut, always recheck the area for

bystanders, animals or obstacles.

FELLING CUT:

Use wooden or plastic wedges (G) to prevent binding

the bar or chain (H) in the cut. Wedges also control

felling (Figure 6-1C).

2. When diameter of wood being cut is greater than the

bar length, make 2 cuts as shown (Figure 6-1D).

WARNING

As the felling cut gets close to the hinge, the tree should

begin to fall. When tree begins to fall, remove saw from cut,

stop engine, put chain saw down, and leave area along

retreat path (Figure 6-1A).

6-2. LIMBING

Limbing a tree is the process of remo

ving the branches

from a fallen tree. Do not remove supporting limbs (A) until

after the log is bucked (cut) into lengths (Figure 6-2A).

Branches under tension should be cut from the bottom up

to avoid binding the chain saw.

WARNING

Never cut tree limbs while standing on tree trunk.

6-3. BUCKING

Bucking is cutting a fallen log into lengths. Make sure you

have a good footing and stand uphill of the log when cutting

on sloping ground. If possible, the log should be supported

so that the end to be cut off is not resting on the ground. If

the log is supported at both ends and you must cut in the

middle, make a downward cut halfway through the log and

then make the undercut. This will prevent the log from

pinching the bar and chain. Be careful that the chain does

not cut into the ground when bucking as this causes rapid

dulling of the chain.

When bucking on a slope, always stand on the uphill side.

1. Log supported along entire length: Cut from top (over-

k), being careful to a

void cutting into the ground

(Figure 6-3A).

2. Log supported on 1 end: First, cut from bottom (under-

buck) 1/3 diameter of log to avoid splintering. Second,

cut from above (overbuck) to meet first cut and avoid

pinching (Figure 6-3B).

3. Log supported on both ends: First, overbuck 1/3 diam-

eter of log to avoid splintering. Second, underbuck to

meet first cut and avoid pinching (Figure 6-3C).

NOTE: The best way to hold a log while bucking is to use a

sawhorse. When this is not possible, the log should be

raised and supported by the limb stumps or by using sup-

porting logs. Be sure the log being cut is securely support-

ed.

6-4.BUCKING USING A SAWHORSE

For personal safety and ease of cutting, the correct position

for vertical bucking is essential (Figure 6-4A).

VERTICAL CUTTING:

A. Hold the saw firmly with both hands and keep the saw

to the right of your body while cutting.

B. Keep the left arm as straight as possible.

C. Keep weight on both feet.

CAUTION

While the saw is cutting, be sure the chain and bar are

being properly lubricated.

wly to release an

y pres

sure in tank. Carefully drain the fuel tank.

2. Start the engine and let it run until the unit stops to

remo

ve fuel from carburetor.

3. Allow the engine to cool (approx. 5 minutes).

4. Using a spark plug wrench, remove the spark plug.

5. Pour 1 teaspoon of clean 2-cycle oil into the combus-

tion chamber. Pull starter rope slowly several times to

coat internal components. Replace spark plug (Figure

7-7A).

NOTE: Store the unit in a dry place and away from possi-

ble sources of ignition such as a furnace, gas hot water

heater, gas dryer, etc.

7-8.REMOVING A UNIT FROM STORAGE

1. Remove spark plug.

2. Pull starter rope briskly to clear excess oil from com-

bustion chamber.

3. Clean and gap spark plug or install a new spark plug

8 - BAR / CHAIN MAINTENANCE

8-1. GUIDE BAR MAINTENANCE

Frequent lubrication of the guide bar (railed bar which sup-

ports and carries the saw chain) sprocket tip is required.

Proper maintenance of the guide bar, as explained in this

section, is essential to keep your saw in good working con-

dition.

SPROCKET TIP LUBRICATION:

CAUTION

The sprocket tip on your new saw has been pre-lubricated

at the factory. Failure to lubricate the guide bar sprocket tip

as explained below will result in poor performance and

seizure, voiding the manufacturer’s warranty.

Lubrication of the sprocket tip is recommended after 10

hours of use or once a week, which ever occurs first.

Always thoroughly clean guide bar sprocket tip before lubri-

cation.

TOOLS FOR LUBRICATION:

The Lube Gun (optional) is recommended for applying

grease to the guide bar sprocket tip. The Lube Gun is

equipped with a needle nose tip which is necessary for the

efficient application of grease to the sprocket tip.

TO LUBRICATE SPROCKET TIP:

WARNING

Wear heavy duty work gloves when handling the bar and

chain.

1. Move the STOP switch down.

NOTE: It is not necessary to remove the saw chain to lubri-

cate the guide bar sprocket tip. Lubrication can be done on

the job.

2. Clean the guide bar sprocket tip.

3. Using the Lube Gun (optional), insert tip of lube gun

into the lubr

ication hole and inject g

rease until it

appears at outside edge of sprocket tip (Figure 8-1A).

4. Rotate saw chain by hand. Repeat lubrication proce-

dure until the entire sprocket tip has been greased.

GUIDE BAR MAINTENANCE:

Most guide bar problems can be prevented merely by keep-

ing the chain saw well maintained.

Insufficient guide bar lubrication and operating the saw with

chain that is TOO TIGHT will contribute to rapid bar wear.

To help minimize bar wear, the following guide bar mainte-

nance procedures are recommended.

BAR WEAR - Turn guide bar frequently at regular intervals

or example, after 5 hours of use), to ensure even wear on

top and bottom of bar.

BAR GROOVES - Bar grooves (or rails which support and

carry the chain) should be cleaned if saw has been used

heavily or if saw chain appears dirty. Rails should always be

cleaned every time saw chain is removed.

OIL PASSAGES - Oil passages on the bar should be

cleaned to ensure proper lubrication of the bar and chain

during operation.

NOTE: The condition of the oil passages can be easily

checked. If the passages are clear, the chain will automati-

cally give off a spray of oil within seconds of starting the

w. Your saw is equipped with an automatic oiler system.

8-2. CHAIN MAINTENANCE

CHAIN TENSION:

Check the chain tension frequently and adjust as often as

necessary to keep the chain snug on the bar, but loose

enough to be pulled around by hand.

BREAKING IN A NEW SAW CHAIN:

A new chain and bar will need chain readjustment after as

few as 5 cuts.This is normal during the break-in period, and

the interval between future adjustments will begin to length-

en quickly.

WARNING

Never have more than 3 links removed from a loop of chain.

This could cause damage to the sprocket.

CHAIN LUBRICATION:

Always make sure the automatic oiler system is working

properly. Keep the oil tank filled with Genuine Factory Parts

Chain, Bar and Sprocket Oil.

Adequate lubrication of the bar and chain during cutting

operations is essential to minimize friction with the guide

bar.

Never starve the bar and chain of lubricating oil. Running

the saw dry or with too little oil will decrease cutting efficien-

cy, shorten saw chain life, cause rapid dulling of chain, and

lead to excessive wear of bar from overheating. Too little oil

is evidenced by smoke or bar discoloration.

CHAIN SHARPENING:

Chain sharpening requires special tools to ensure that cut-

ters are sharpened at the correct angle and depth. For the

inexperienced chain saw user, we recommend that the saw

chain be professionally sharpened by the nearest

Authorized Service Center. If you feel comfortable sharpen-

ing your own saw chain, special tools are available from the

nearest Authorized Service Center.
